Torbjørn Lindahl 258d1ecc60 Fix netboot: hardcode config values, simplify boot chain
- Hardcode ROOT_URL and OVERLAYROOT in netboot script
- Remove cmdline parsing that was failing silently
- Simplify boot.ipxe to chain to netboot.ipxe
- Add rebuild-initramfs.sh helper script

Resolves kernel panic caused by cmdline parsing issues.
